If your little one is just the berry sweetest, this theme is as cute as it gets. A Berry First Birthday is perfect for spring or summer and brings together rustic charm and fruity fun.
Think red gingham tablecloths, strawberry garlands, and little berry baskets as centerpieces. A chalkboard sign that says “Our Berry Sweet Girl is One” makes for a perfect photo op.Use strawberry cut-outs, balloons in red, pink, and green, and even a high chair banner with little berries on it.

Princess or Fairytale Theme
A first birthday is the perfect excuse to bring out the tiaras and go full-on fairytale. Whether you go with a classic princess look or a specific character-inspired party (like Cinderella or Belle), the focus is on sparkle, elegance, and a touch of magic. Think tulle table skirts, gold accents, and plenty of pink or lavender.
A castle-shaped cake or cupcakes with tiny crowns will charm both kids and adults. Personalized touches—like a storybook photo timeline of baby’s first year—help turn this theme into a fairytale you’ll always remember.
Here is all the princess party stuff you can find for this party idea!
“One-der the Sea” Mermaid Theme
This under-the-sea theme combines soft aquatic colors like seafoam green, lilac, and shimmering blues with all things mermaid. Shells, pearls, and glittery scales can bring the decor to life, while the food table can feature clever options like “seaweed” (green veggie sticks), “fish food” (goldfish crackers), and cupcakes topped with mermaid tails. A bubble machine adds a fun sensory element for little ones, and a soft play area with ocean-colored mats or pillows helps keep things safe and interactive.

Boho Chic or “Wild One” Theme
For parents who love a more earthy, laid-back aesthetic, a boho or “Wild One” theme is effortlessly stylish. Think natural textures, muted tones, and whimsical details like dreamcatchers, pampas grass, and wooden signage. Decor can include woven rugs, rattan chairs, and a DIY balloon arch in soft blush and cream. Simple, rustic food like fruit cups, mini muffins, and a “naked” cake (lightly frosted for that rustic feel) ties the theme together. Add a cozy teepee or reading nook to give the party space a relaxed, magical vibe.

Twinkle Twinkle Little Star ⭐
This one had me emotional before I even started planning it. “Twinkle Twinkle Little Star” is such a sweet lullaby that so many of us sing to our babies—and it makes the perfect dreamy theme for a nighttime or winter celebration.
Use soft hues like gold, white, navy, and lavender. Hang paper stars from the ceiling or string them across the walls with fairy lights.Create a backdrop that says “Twinkle Twinkle Little Star, One Year Old Is What You Are” (yes, I cried a little just writing that).
It’s whimsical, heartfelt, and a perfect theme for reflecting on just how fast that first year has flown by.

Sweet as a Peach (or Strawberry, or Bee!)
Fruit- and nature-inspired themes are adorable for a first birthday and easy to personalize. A “Sweet as a Peach” party might feature soft peach tones, gingham tablecloths, and peachy desserts. A strawberry theme brings bold pops of red and green, while a bee-themed “Little Honey is One” party offers bright yellow decor, honeycomb patterns, and cute sayings like “Buzzing into One.” These themes work especially well for outdoor parties and lend themselves to creative treats and photo setups.

Final Touches for the Big Day
No matter the theme, the best parties focus on the details that make guests feel welcome and create keepsake moments.
A simple milestone board with baby’s current stats, favorite words, and quirks is always a crowd-pleaser.
Soft play areas, sensory toys, or even a quiet storytime space keep little guests happy and engaged.
And for the grown-ups, thoughtful touches like labeled snacks, themed drinks, or a small coffee and tea station go a long way.
The most important part of a first birthday celebration is celebrating all the love, growth, and magic that the past year has held.
Whether you go all out with a themed party or keep it sweet and simple, it’s a chance to soak up the joy of this once-in-a-lifetime moment—and to create memories you’ll treasure for years to come.
